Investigation on Tribological Characteristics of Al 7075 MMNC: Behavior of Micro- and Nano-Sized Composites

This study investigates the mechanical properties and wear behavior of Al 7075/Al2O3/SiCNP composites. The hybrid composites are manufactured using stir casting technique. In this work, 7075 alloy is reinforced with five different weight fractions Al2O3 a constant SiCNp, an average particle size 50 nm. aluminum metal matrix examined through surface morphology X-ray diffraction (XRD) patterns to identify material behavior. characteristics pin-on-disk test. Wear measurements performed by varying loads, sliding speeds, distances. results reveal that 4% particulates exhibit superior properties. rate coefficient friction (COF) decrease increase in reinforcement content.
